A compact sound processing system and method for use with a plurality of sound radiators. A microcontroller accepts a plurality of user-selected speaker equalization and space equalization settings and receives a paging control signal from a telephone interface. An analog mixer combines music signal inputs and a paging signal. A digital signal processor generates and filters masking noise, and processes the masking noise and combined music and paging signals based on user-selectable settings for distribution to the sound radiators. An audio amplifier modulates and amplifies the output signal from the digital signal processor, and delivers the output signal to the sound radiators via a transformer in defined zones. The sound radiators can be flat panel sound radiators or conventional type speakers. A masking filter used with the masking noise generator can be programmed to shape the virtual random noise generated by decreasing the noise at a constant rate over the frequency range of human speech. A paging over music function reduces the music sound level by a preset amount whenever a paging control signal is received. A talkback controller is also provided to enable an individual to respond to a page using the sound radiator as a microphone.
